* `http`: sistemas de autenticación HTTP estándar, incluyendo:
  * `bearer`: un header `Authorization` con un valor de `Bearer ` más un token. Esto se hereda de OAuth2.
  * Autenticación básica HTTP.
  * Digest HTTP, etc.
* `oauth2`: todas las formas de OAuth2 para manejar la seguridad (llamadas "flujos").

그렇게 하면 몇 분 또는 몇 시간 만에, 응답에 걸린 시간만을 이용해(우리 애플리케이션의 “도움”을 받아) 올바른 사용자명과 비밀번호를 추측할 수 있게 됩니다.

#### `secrets.compare_digest()`로 해결하기 { #fix-it-with-secrets-compare-digest }

하지만 우리 코드는 실제로 `secrets.compare_digest()`를 사용하고 있습니다.

요약하면, `stanleyjobsox`와 `stanleyjobson`을 비교하는 데 걸리는 시간은 `johndoe`와 `stanleyjobson`을 비교하는 데 걸리는 시간과 같아집니다. 비밀번호도 마찬가지입니다.

#### 「專業」的攻擊 { #a-professional-attack }

當然，攻擊者不會手動嘗試這一切，他們會寫程式來做，可能每秒進行上千或上百萬次測試，一次只多猜中一個正確字母。

但這樣做，幾分鐘或幾小時內，他們就能在我們應用程式「協助」下，僅靠回應時間就猜出正確的使用者名稱與密碼。

#### 用 `secrets.compare_digest()` 修正 { #fix-it-with-secrets-compare-digest }

但在我們的程式碼中實際使用的是 `secrets.compare_digest()`。

簡而言之，將 `stanleyjobsox` 與 `stanleyjobson` 比較所花的時間，會與將 `johndoe` 與 `stanleyjobson` 比較所花的時間相同；密碼也一樣。

如此一來，在應用程式程式碼中使用 `secrets.compare_digest()`，就能安全地防禦這整類的安全攻擊。

            MessageDigest digest = MessageDigest.getInstance("SHA-256");
            return digest.digest(bindingInfo);
        } catch (NoSuchAlgorithmException e) {
            throw new IOException("SHA-256 not available", e);
        }
